DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The following further describes the specific embodiments of the present utility model with reference to the drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0017] Combined with Figures 1 to 4A burner head shown, including an inner shell 2, characterized in that a separator 9 is detachably installed inside the inner shell 2, so that a combustion chamber 3 and a pilot chamber 10 are formed inside the inner shell 2. The combustion chamber 3 and the pilot chamber 10 are in communication with each other, and an ignition induction needle module 11 is arranged inside the pilot chamber 10. In this embodiment, the inner shell 2 is separated by the separator 9 to form the combustion chamber 3 and the pilot chamber 10, and then the ignition induction needle module 11 is placed inside the pilot chamber 10, thereby preventing the ignition induction needle module 11 from being burned in the combustion chamber 3 all the time, improving the service life of the ignition induction needle module 11. Moreover, after the flame in the combustion chamber 3 is extinguished, the pilot chamber 10 can be used to retain the pilot flame, and there is no need to re-ignite every time it is used.
[0018] In this embodiment, the inner shell 2 includes a combustion cylinder 7 and a pilot cylinder 8. The inner diameter of the combustion cylinder 7 is larger than that of the pilot cylinder 8. The separator 9 is erected on the inner wall of the bottom surface of the combustion cylinder 7. The combustion chamber 3 is arranged inside the combustion cylinder 7, and the pilot chamber 10 is arranged inside the pilot cylinder 8. The inner shell 2 is embedded in the outer shell 1, and an air chamber 4 is formed between the outer shell 1 and the inner shell 2. Both the combustion chamber 3 and the pilot chamber 10 are in communication with the air chamber 4. The ignition induction needle module 11 penetrates through the outer shell 1 and is connected to the pilot cylinder 8. By erecting the separator 9 between the combustion cylinder 7 and the pilot cylinder 8, large foreign objects are prevented from falling into the pilot cylinder 8. At the same time, the combustion chamber 3 and the pilot chamber 10 can be separated, and the separator 9 can be taken out conveniently, so as to facilitate the cleaning of the inside of the burner head.
[0019] Specifically, the separator 9 of this embodiment includes a separator plate 12. A handle 14 is arranged on one side of the separator plate 12 close to the combustion chamber 3. Communication holes 15 located on the separator plate 12 are arranged around the handle 14. The separator plate 12 can be lifted by the handle 14 for easy installation and disassembly. Moreover, the combustion chamber 3 and the pilot chamber 10 are in communication through the communication holes 15. When the flame in the pilot chamber 10 does not go out, the ignition efficiency of the combustion chamber 3 is higher.
[0020] In some embodiments, a filter sheet installation groove 13 is formed on the separator plate 12. The handle 14 and the communication holes 15 are both located inside the filter sheet installation groove 13. A filter net 16 is embedded and installed inside the filter sheet installation groove 13. A handle hole corresponding to the handle 14 is formed on the filter net 16. Foreign objects can be further prevented from falling into the pilot chamber 10 through the filter net 16, and the filter net 16 can be made of a stainless steel punched sheet.
[0021] The ignition induction needle module 11 of this embodiment includes a ceramic tube body 19 penetrating through the housing 1 and the ignition tube 8. An ignition needle 20 and an induction needle 21 are installed through the ceramic tube body 19. One ends of the ignition needle 20 and the induction needle 21 extend to the outside of one end of the ceramic tube body 19, and the extended sections of the ignition needle 20 and the induction needle 21 are located in the ignition cavity 10. By integrating the ignition needle 20 and the induction needle 21 in the ceramic tube body 19, the installation is more convenient. Moreover, the induction needle 21 can be used to sense the ignition in the ignition cavity 10. If the ignition goes out, it can be fed back to the system through the induction needle 21 to initiate the extinguishing protection action. In addition, the parts of the ignition needle 20 and the induction needle 21 extending outside the ceramic tube body 19 are located at the lower inner end of the ignition cavity 10 to further prevent the ignition needle from being burned by the ignition for a long time.
[0022] A gas pipe connection hole 17 is formed in the combustion tube 7 of this embodiment. A main gas pipe 5 communicating with the combustion cavity 3 is arranged in the gas pipe connection hole 17. A fire gas pipe connection hole 18 is formed in the ignition tube 8. A fire gas pipe 6 communicating with the ignition cavity 10 is arranged in the fire gas pipe connection hole 18. The main gas pipe 5 supplies gas to the flame in the combustion cavity 3, and the fire gas pipe 6 supplies gas to the ignition. Air holes communicating with the air cavity 4 are formed in the side walls of the combustion tube 7 and the ignition tube 8, so that the gas can be mixed with air for combustion, making the combustion more complete.
[0023] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions, and variations to these embodiments still fall within the protection scope of the present invention.
